Description
technical field [0001] The invention relates to the technical field of electrolytic grinding, in particular to an inner hole processing system and method based on electromagnetic ultrasonic vibration composite energy field. Background technique [0002] The inner hole structure is widely used in many engineering applications, including: aerospace engine air film cooling space, small holes on precision instruments, micro holes on chemical fiber boards, etc. The surface roughness of the inner hole significantly affects the forming quality of the small hole, so the technical requirements for the precision micromachining of the inner hole are getting higher and higher. [0003] Electrolytic grinding has significant advantages in many small hole processing methods. The advantages of this processing technology are: it is not limited by the strength, hardness and toughness of the material, and there is no residual stress on the workpiece processing surface. However, due to the tur...
